This book is an accumulation of my DuckDB smaller books. The 300+ pages covers a range of topics. The primary is of course SQL (Structured Query Language), which you apply to interact with the database. Once you are familiar with SQL, the rest of the topics, eleven in total, will further enhance your DuckDB skills.
The eleven topics (listed on the book inside cover page) Join Types, Custom Functions, Regular Expression, Data Analytic, OLAP (OnLine Analytical Processing), JSON Data (JavaScript Object Notation), Sequence Object, Designing Schema, Database Catalog, Data Ingestion, and Back-up & Restore.
This is a practical no-nonsense book, every piece of a subject is accompanied by examples you can try yourself. When you finish with the book, you will have equipped yourself with practical skills to apply in a real world project.
